Help reading players competitive ranks

hi, i'm pretty new to coding with c++.
So far i've managed to make a bhop script and a basic triggerbot in c++ with no tutorials or c+p, but now i'm trying to make something that can read player's mm ranks. i've been trying to work it out today with no luck. i've been using m_iCompetitiveRanking (0x1A38) and m_iGameResources (0x2E5D9CC) to try and read a player's rank, but have not been able to receive values other than 0. if someone could point me in the right direction of how I should be reading someone's rank that would be great

it was giving 0 because I was testing it in a dm. after testing it in a GOTV match it now returns the correct ranks
